The upwardly extending members 36 and 27 carry suitable supporting brackets 44 and 45 respectively wh ch have formed therein openings sufficiently large to recelve the respective pivot housings 43, and a flange ring 46 is 35. Suitable thrust washers 51a are carried on shaft 35 between the hubs 48 and 50 and the respective bearings 39 and between the opposite ends of the bearings 39 and suitable washers 52 carried on the shaft adjacent the respective sprockets 37, these thrust washers being of the non-lubricating type and preferably of the type known Suitable oil seals'53 of any conventional construction are provided on'opposite .ends of the respective bearings 39 for well known purposes.

A driven shaft 54 is rotatably carried in suitable bearings 55 in spaced relation with respect to driving shaft :35, see also Fig. 6. The respective bearings 55 are secured by means of suitable bolts 56 .in channel-shaped supporting members 57, the members 57 having formed therein aligned slots 58 for receiving the bolts 56 and carrying laterally extending bracket 59, Fig. 2, for receiving subbearings 55. It will be appreciated that by loosening the 'respective'bolts 56' that the bearings 55 can be moved sutficientlyforwardly or rearwardly within the limits of 'slots 58 until the proper position for shaft 54 with respect to shaft 35 is reached. The respective bearings are then locked in this adjusted position by tightening bolts 56 and locking movement of bolts 60 with respect to brackets 59 by lock nuts 61 threaded on bolts 60 on opposite sides of brackets 59. Suitable locking means 61a are received spective bearings off the shaft 54.

Driven sprockets 62 having hub portions 63 are keyed to the shaft 54 in spaced relationship and in alignment .porting the apron of vines being carried rearwardlywhile still permitting any dirt picked up with thevines 'to fall to the ground upon being shaken loose from the vines as well as aiding in stripping the apron of vines from the pick-up fingers adjacent the discharge end of the pick-up elevator.

The crop defining supporting members 68a are secured rearwardly adjacent the side members 67 as by the bolts 69'as previously suggested and forwardly the crop-defining ,members are secured'to the respective side members by 'stantially rearwardly extending bolts 60 of the respective by 'the opposite ends of the shaft and locked thereon by pins 61b for preventing axial displacement of the rewith the driving sprockets 37, and pins 64 are received 4 by the 'respective hubportions 63 for preventing axial movement of the respective sprockets. 'A tine rod support 65 is secured to the shaft 54 substantially intermediate the sprockets62 by means of a suitable pin 66 and is substantially cylindrical in shape and of a diameter substan- The channel-shaped brackets 57 for carrying the bearings of the driven shaft'54 are secured as by welding or the like adjacent the forward ends of. a pair of side members 67, and the members 67 have formed adjacent their rearward ends, openings for receiving the respective bearings 39, Fig. '5. Retainer rings 68 are received on the opposite sides of the pivot housings 43 and suitable bolts or the like 69 rigidly secure the retainer rings 68 and'side' members 67 and crop defining supporting members '68a'to opposite sides of the respective pivot housings 43. It will be appreciated that upon swinging movements being imparted to the side members 67, that the pivot housings 43 will turn or rotate in the flanged rings 46 so as to permit the pick-up elevator to be swung from an operative to an inoperative position.

Endless drive chains 70 are carried by the sprockets 37 and 62 and, attached to the chains 70 at spaced intervals along thelinks thereof are a plurality of transverse tine rods 71 which are provided to carry a plurality of pick-up fingers 72 of any suitable or conventional construction. The fingers 72 are comprised of flexible wire which is coiled around the tine-rods 71 and they have their central sections or bights 73 engaged with fastening means of rivets or any other suitable means 75a so that the members move as a unitary structure. The crop-dei picked up, as well known in the art.

As previously suggested the adjusting means 15; is provided for regulating the position or inclination of the pick-up elevator 14 with respect to the ground. More specifically, the adjusting means comprises in the present instance a transverse rock shaft 78,- Fig. l, rotatably supported in suitable bearings carried in brackets 79 extend ing upwardly from the fore and after frame members 20 and 21 respectively adjacent forward ends thereof, said rock shaft having fixed adjacent the respective ends thereof suitable rearwardly extending rock arms 80 and 81 respectively. Links 82 are pivotally secured between the re'spective' ends of the rock arms 80 and 81 and the corresponding side members 67'of the pick-up elevator 14, and a control lever 83 is secured by means of suitable bolts or the like 84 to a flange 85 of the rock shaft 78. The control lever 83 is swingable adjacent a rearwardly extending toothed arcuate portion 86 which is bolted by means of bolts 87 to an upwardly extending bracket 88 secured by welding or the like to the front frame mem- 'ber 22 of the movable frame. The'control lever carries a suitable detent mechanism 89 of any conventional construction which, has a resiliently urged dog 90 which engages with the teeth of the arcuate portion 86 when the detent mechanism is in an engaged position as well known in the'art. It will be appreciated that the pick-up elevator 14 is biased so as to swing downwardly about the axis of the driving shaft 35 and this downward movement is prevented only by the dog 90 of the detent mechanism 89 as it engages with the teeth of the arcuate portion 86'so as to prevent swinging movement of .the control lever 83 and consequently rotation of the rock shaft 78.

When it is desired to move the pick-up elevator 14 into a a raised or transport position, the operator, by moving the dog 90 of the detent mechanism 89 out of engagement with the teeth of the arcuate portion 86, can swing the control lever 83 forward and consequently rock the rock shaft 78 sufiiciently to lift the pick-up. elevator into transport position, and then, by re-engaging the dog 90 of the detent mechanism 89 between the teeth of the arcuate portion 86 so that the control lever 83 is again locked against swinging movement, the pick-up elevator 14' can be locked in said raised or transport position.

To aid in moving'the pick-up elevator 14 intora raised or transport. position, a suitable counterbalance spring 90a is anchored between a bracket 91, securedto' the fore and aft member 21 adjacent the upwardly extending "member 27 and a downwardly extending rock arm 92 fixed to the rock shaft 78 adjacent the rock arm 81. n, In

formed therein transverse slots 109.

the operation of this pick-up and windrowingmanhine the pick-up elevator' 14, in operation-issupported at an inclination so that: thelowermost pick-up fingers barely touch the ground. To permit the operator to swing the pick-up elevator 14' downwardly into an operativepositi'onwithout endangering the: pick-up: finger-spa limit; stop 93 is provided, see also Fig. l0.- This liintt-stop includes a rearwardly extendingrock arm 94 fixed to the rock shaft 78 adjacentthe rock arm 81-. This rock arm has securedadjacentthe end thereofa threaded nutv 95' which receivesa threaded screw 96 therein and the rock. arm M le-positioned on'therock shaft 78 so as to" swing in the vertical: planexof the fore and aft frame member'ZL lt willibe appreciated that by permitting: the pick-upielevator 14 to be biased or swun'gdownwardly in a manner as previously described, that the threaded screw,'upon being properly adjusted, will, upon'being moved .into contact with the frame member 21 prevent further downward movement of pick-up elevator'14' when the dog 90 is not engaged with the teeth of arcuate'portion 86; This. adjustable screw 96 can be. adjusted so that the pick-up elevator 14 can be stopped from further downward swinging movement when the pick-up fingers are either just barely in contact with the ground or are positioned several inches above the ground, the condition of the vines being; picked up and the condition of. theground being traversedbeing determinative of the setting of .the adjustable screw 96;

The pick-up elevator 14.is driven. in: the'dire'ctionindicated' by the driving means 16 as previously suggested. The driving means 16 includes in. the present: instance a drivenshaft 97 which is journaled in suitablebearings carried in a housing 93. The housing 98 is secured by means of abracket 99 to the front frame member 22 substantially intermediate the ends" thereof so as to position the: driven shaft 97 substantially longitudinally with respect to" movement of the machine. The driven shaft 97 has fixed adjacent the rearward end thereof a V-belt jackshaft 161 is rotatably journ'aled in a housing 102,

and the housing 102 is secured as by welding or the like men attaching bracket 103 which is adjustably carried by a supporting bracket 104 extending laterally flOllI the upwardly extending frame member 26 and secured thereto-as by belts or the like 105, the jack' shaft 101 being transvers'ewith respect to' the direction of movement of the machine. A V-belt pulley 10'6 is' fixed adjacent the lateral end of the jack shaft 101 and is drivingly' connected by means of a suitable V-belt 107 to the pulley 106'- of the driven shaft 97. Adjacent the rightend of the transverse'f'rame member 22 is secured as by welding or the like a suitable supporting bracket 198 which has A substantially channel shapedbrack'et 110 is carried by the bracket I08 byjmeans' of bolts 111 which are received by the respective slots 109 so as to' permit the channel shaped bracket to be moved within the limits of the slots when the respective' bolts are loosened. A slot 112 is formed in the bracket 108 and a pin 113' extending forwardly from the channel shaped bracket 110' is received by the slot 112. AI-n-eyebolt' I14 iss'ecured' to the pin 213- and extends inwardly for locking thebraeket 11%? in adjusted position by means of lock nuts 115 on opposite sides of av flange of the supporting: bracket 103 as well known in the art. Suitable V-beltpulleys H6 and It? are rotatably' supported by the bracket 11(i'in spaced. relationship, the respective' pulleys being so positioned with respect to the policy 100' and the pulley 106- as to'chan'ge the direction of travelof the V-belt 167. More specifically the V-be-lt '11 isurained: around'the pulley s and extends laterally diererfronr whence it is'tmined around" the; pulley 116,

The pulley 116 changes the' direction of travel of" the V-belt 107 and directs the same rearwardly in alignment with pulley 106 the belt beirzgitrained around-pulleylflti and then. forwardly and around the pulley 117 so asi to again extend transversely in alignment with the pulley 100. Adjacent the inner end of the jack shaft 101 is fixed a driving spocket 118 which is'positioned in. substantially vertical alignment with the driven sprocket 47 of the driving shaft 35 and a suitable endless chain 119 is trained around these respective sprockets for imparting the rotary motion of the jack shaft 101v to the driven sprocket 47 and subsequently to the drivingshaft 35.

The deflector 18 is spaced rearwardly from the. discharge end of' the pick-up elevator 14 as previously suggcsted and comprises in the present instance a substantially rectangular framework 120 preferably formed: of angle irons or other suitable structural members, an'd a suitable meshed material such. as wire 121 or the like" is secured to the rectangular frame so as tov provide" adeflecting surface therefor. The rectangular frame 120' is swingably carried by inwardly extending pins 122' of s porting arms 123, the pins 122 being received in aligned slots 124formed in the rectangular framet120. The supporting arms 123 are secured to the respective su porting'brackets 44 and 45 in vsubstantially parallel rearwardly inclined position by means of bolts on the like 125', and locking plates 126' provided with: slots 127' are secured to the respective'supporting arms 123'adjacent the rearward ends theerof. The rectangular frame 120'has laterally extending pins 128 which are received by the slots 127 of the lockingplates 126 for locking. the deflector against swinging about the pins 122 in its properly inclined position with respect to the pick-up elevator 14. It will. be appreciated that the deflector 18 can be tilted about the pins 122' by exerting a' force upwardly against the deflector sufiiciently to move the pins 128 out of engagement' with the slots 127, the deflector being then free to swing about the'pin's-122 between the supporting arms 123. The supporting arm 123 adjacent the supporting bracket 45 is provided" with downwardly extending fingers 129' for preventing the discharge of vines in a direction laterally of said fingers as will be more fully appreciated hereinafter.

The conveying platform 17 is carried rearwardly' of the pick-up elevator 14 and below the deflector l d-for conveying the apron of vines delivered thereupon tr'ansversely for forming a windrow laterally of the pick-up elevator as previously suggested. The conveying. platform is formed in the present instance of channel-shaped side members 139' and 131 which are rigidly held in parallel spaced relationship, and adjacent the: respective ends of the members 130 and 131' are journaled' in suitable bearings 132 substantially parallel and fore and aft extending shafts 133 and 134; the driving shaft 134 having fixed thereon spaced driving sprockets 135 which are" in alignment with driven sprockets 136' fixed to the: driven shaft. 133, see also Figs. 7 and' 8. The aligned sprockets receive" endless chains 137 of any suitable or well-known construction and secured between the links of the chains are spaced substantially parallel push bars 138 for moving the material, such as peanut vines, in one direction. An open slatted bottom 139' is so positioned between the respective shafts 133 and 134' that the push rods urging the" vines in one direction operate on the open slatted bottom, this bottom providing means wherein lo'osedirt discharged downwardly by the deflector 13 along 'witti the vines can. filtrate downwardly through. the slatted bottom and fall upon the ground instead of in the'windrow being formed. The channel shaped memb'er130'is'provided with depending brackets 140' which have formed therein downwardly and rearwardly extendinglslots 14-1.

- The channel shaped member 131 has secured theretoas by welding or the like suitableangular shaped tabs 142. The fore and' aft: extending frame members 2'0 and 21 have fixed adjacent the rearward ends thereof late'tally. extending pins 143 and the conveying platform. 17 upon being tilted upwardly and rearwardly, see Fig. 9, .can receive the pins 143 in the slots 141 of the brackets 140. After the pins 143 are received by the slots 141 the conveying platform can be swung downwardly until the tabs 142 are supported by the rear transverse frame member 23, 'the conveying platform being then supported in a substantially horizontal position. For driving the shaft "134 and consequently the chains 137 and push rods 138, a V-belt pulley 144 is fixed to the hub of the driving shaft 35 and a V-belt pulley 145 is fixed to the rearward end of the shaft 134. A V-belt 146 is trained around the pulley 144 and the pulley 145 and a .belt tightener 147 including a bracket 148 rotatably carrying a pairof laterally spaced V-belt pulleys 149 is swung rearwardly against the V -belt 146. Suflicient slack is allowed in the V.-belt 146 so that upon tightening the belt as by a link 150 engaging a pin 151 carried by the upwardly extending member 27 in a slot 152, the pulleys 149 are moved sufliciently rearwardly to be in substantially vertical alignment with the pulley 145. It will be appreciated that upon rotation of the driving shaft 35 of the pick-up elevator 14, that the pulley 144 will be driven in a like direction so as to drive the pulley 145 so that the push rods move so as to urge the vines to the right toward the discharge end of the platform.

. Adjacent the discharge end of the conveying platform 17 is rotatably carried a stripping roll 153 in suitable bearings 154 laterally spaced from the driven shaft 133 by means of laterally extending brackets 155 secured to the channel shaped members 130 and 131 respectively. The stripping roll 153 is provided with a plurality of substantially radially extending flanges 156 and a driving sprocket157 .is fixed to the rearward end of the stripping roll 153 and is drivingly connected by means of a suitable driving chain 158 to a driving sprocket 159 fixed to the rearward end of the shaft 133 in alignment with the sprocket 157. It will be appreciated that upon rotation of the driving shaft 134, in a manner as previously described, that the driven shaft 133 will be rotated in the same direction by means of chains 137 and consequently the stripping roll 153 will be rotated in the same direction as shaft 133, the stripping roll 153 stripping the vines off the discharge end of the conveying platform in a manner well known in the art.

. A suitable upwardly extending shield 160 having downwardly extending locking pins 161 is carried by the channel shaped member 130 and is positioned thereon by insertion of the locking pins 161 in aligned openings formed in the channel shaped member 130, the shield being so positioned as to deflect any vines or other like material picked up by the pick-up elevator 14 from being thrown rearwardly beyond the conveying platform 17 and the deflector 18. The deflector as previously suggested is capable of being tilted into an out-of-the-way position so that upon installing the conveying platform 17 and the shield 160 upon the machine in a manner as previously .suggested, the deflector 18 upon being tilted allows the operator sufiicient space to work in. The deflector is also provided with suitable tabs 162 which overlap the shield 160 when the deflector is locked in its proper position.

, In operation the driving shaft 35 is driven at a speed ,suflicient to throw the apron of vines picked up by the pick-upfingers 72 rearwardly against the deflector with a force suflicient to disintegrate any clods or clumps of 'dirtclinging to the vines, a goodly portion of this dirt upon being disintegrated passing through the meshed deflecting surface 121.. The vines upon contact with the deflector 18 are deflected downwardly upon the conveying platform 17 whereupon they are urged to the right by the push rods 138, the dirt which did not pass through the meshed deflecting screen 121 being filtered so as to pass through the slatted bottomv 139 rather than being thrown into the resulting windrow which is formed to the right of the-pick-up elevator 14.

'In the embodiment of the invention shown in Fig. ,10, the conveying platform 17 together with the, shield 160 have been'removedfrom the machine andgathering grates 163 a're provided for forming a windrow rearwardlyv of the pick-up elevator 14. More specifically the gathering grates 163 include in the present instance rearwardly, extending supporting posts 164 which are carried :by post holders 165 which in turn are securedas by bolts or the like 166 to the upwardly extending members 26 and 27 respectively, the supporting posts 164 having fixed thereto inwardly extending fingers 166a for receiving the vines being deflected downwardly by the deflector 18, in a manner as previously described. Suitable pins 167 are inserted in the post holders 165 and the supporting posts 164 for locking the posts 164' against rotation therein. a

A suitable sheet metal housing 168, Fig. 1, is carried by the front frame member 22 for enclosing that portion of the V-belt 107 adjacent the pick-up portion of elevator 14 for preventing the possibility of the vines becoming entangled with the V-belt 107.

These and other modifications will now be apparent to those skilled in the art, and it is expressly understood that all such modifications are within the comprehension of the present invention.
